#### 37.5.1 Understanding configuration macros and variables

A configuration variable is a macro variable that looks like this:

    $$[Section]Key

where the components of the variable are as follows:

Section | Name of a configuration-file section.
Key | Keyword, format name, or other identifier that appears to the left of the equals sign in a configuration setting under [Section].

A configuration macro is a DITA2Go macro that employs a configuration variable, either to access or to change the value of a configuration setting.

This is all you need to access the current value of a configuration setting. To change the value of a setting, see §42.2.4 Assigning values to configuration variables.
